ROLL FOR SPINNING-MACHINES.

SPECIFICATION formingpart of Letters Patent No. 692,855, dated February11, 1902.

Application filed April 30, 1901.

To all whom it may concern:

Be it known that I, JAMES B. HUDSON, a citizen of theUnited States,residing at Char lotte, in the county of Mecklenburg and State of NorthCarolina, have invented new and useful Improvements in Rolls forSpinning- Machines, of which the following is a specification.

My inventionis designed for the production of a roll, spindle, orcylinder having'a cov ered surface intended especially for use inconnection with spinning machinery. The same is particularlydesigned forthe production of a spinning roll, the object of the same being toprovide a covering for the working surfaces thereof which shall have allthe advantages of the leather or sheepskin cot now generally employedand which will overcome many of the disadvantages thereof, the noveltyresiding in the particular covering material employed and the means forapplying the same to the core of the roll.

The invention consists of a rollmade up of a metallic core, a layer ofyielding fabric or fibrous material cemented or glued to the sur-* facethereof, and a layer of flexible inelastic Fig. 3 is atransverse sectionof the roll. 4 is a similar section showing the two layers waterproofmaterial separate from but ce-l mented or glued to the outer surface ofsaid layer of fibrous material with the longitudinal edges thereofabutting against each other and the whole firmly and compactly rolled orotherwise compressed together.

The invention also consists of certain fea-- tures and details ofconstruotion,which will be hereinafter more fully described and claimed.

In the drawings forming apart of this specification, Figure l is aperspective view of a spinningroll made according to my invention.

Fig. 2 is an elevation of the same with the two layers of coveringmaterial in section. Fig.

of covering material disunited from the central core and from eachother. Fig. 5 is a transverse sectional view of the machine I employ forapplying the covering material to the roll, and Fig. 6 is a plan view ofthe same.

Like reference-numerals indicate like parts in the different views.

While I have shown in the drawings a spinning-roll made according to myinvention, I desire it to be understood that the invention s mi No.58,146- m0 modelis not limited to spinning-rolls, but applies toslubber-rolls,speeder-rolls,and the like. The central metallic core ,lhas cemented or glued to the outer surface thereof a layer 2 M yieldingfabric or fibrous material, and on the outsideof the layer 2 or" fibrousmaterial is cemented or glued a layer 3 of enamel oil-cloth core 1slipping or turningmovement of the same on said core is' effectuallyprevented. The oil-cloth layer 3 is likewise formed from a rectangularblank, and when'i'n place .upon the layer 2 of fibrous material themeeting edges 5 thereof lie in close contact with each other with nooverlapping or projecting por-' tions, which cause or produceanunevenness in the outer surface of the roll. Furthermore, by reason ofthe fact that the oilf-cloth layer 3 is cemented to the layer 2 offibrous material slipping or turning movement of the covering as a wholeon the core is effectually prevented.

- Forcove'ringmyimprovedspinningorother roll I am now employing at myworks a machine constructed in accordance with that shown in Figs. 5 and6 of the drawings. This machine consists of .three cooperating pressure-rollers 6, 7, and 8, the rollers 6 and 7 being mounted in suitablebearings in a framework 9and having on their projecting ends gears 1010, meshing with an intermediate gear 10*,so that said rollers 6 and 7r0 tate in unison and in the same direction. The roller 7, on the endthereof opposite the gear 10, is provided with a" pulley 11, by means ofwhich the same may be driven from any suit-able source of power. Theroller 8 is loosely mounted in the free end of a lever 12, fulcrumed ata point intermediate its ends upon a bracket 13, secured to the frame 9.Theouter or projecting end of the lever 12 is connected through thepitman 14 with a treadle or foot-lever 15. In applying the covering tothe core 1 by this machine the exterior surface of said core has appliedto it the cement or glue, and the layer 2 is placed upon the same byhand. The core 1, with the layer 2 applied, is then introduced into themachine, as shown in Fig. 5 of the drawings, the same resting upon therollers (3 and 7. Of course to insert the partially-covered core 1 intothe machine it is necessary to raise the roller 8, which may beconveniently done by merely depressing the treadle or foot-lever 15.When properly seated in the machine, the heavy roller 8 is permitted tofall by releasing the pressure on the lever ortreadle 15, and then,through the application of power to the pulley 11 on the end of theroller '7, both rollers 6 and 7 and through them the partially-covcredcore 1 and the roller 8 are caused to turn. This turningmovement, withthe heavy pressure-roller 8 in contact with the outer surface of thelayer 2 on the core 1, forces said layer into adhering contact with saidcore, tightly compressing the same and smoothing out any unevennessesthat may be in the fibrous material of which the layer2 is made.Afterward the core 1, with the layer 2 cemented thereto, is removed fromthe machine and cement or glue applied to the exterior surface thereof.When this has been done, the oil-cloth layer 3 is applied by hand to theoutside of the layer 2, and the core 1, with the layers 2 and 3 thereon,is again introduced into the machine between the rollers- 6, 7, and S.The oil-cloth layer 3 is then, through the action of the machine-rolls6, 7, and 8, tightly compressed and forced into close adhering contactwith the layer 2 of fibrous material. The ends 5 of said oil-cloth layerare also brought into close contact with each other, so that no unevenplaces or projections are formed on the exterior surface of thecompleted roll.

A spinning or other roller constructed according to my invention isprovided with a regular even working surface equally well adapted forthe purpose for which it is designed as the old leather or sheepskincovered roller. Furthermore, the expense of producing my improved rolleris much less than that of the ordinary cotcovered roll, and danger ofslipping of the covering on the central core is absolutely prevented.This latter is one of the main objections to the old leathercoveredroll. It has been found in practice that these rolls after they havebeen in use for a short while will, due to the pressure which is appliedto them, slip upon the rollercore and be rendered absolutely useless.This tendency to slip or creep on the core is materially increasedduring damp weather, owing to the absorptive qualities of the materialof which the cot is made. With my improved roll it is absolutelyimpossible for the same to absorb moisture and be rendered inoperativeon this account. In fact, the same may be allowed to remain for aconsiderable period of time in a body of water Without any deterioratingeffects Whatever being noticed.

It is necessary that the outer layer 3 of my covering bewaterproof,fiexible, and inelastic, and I have found that the bestmaterial for the purpose is enameled oil-cloth. This may be used witheither the smooth or pebble finish, and it may be that other substitutesfor the same may be found.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A roll, consisting of a core, a layer of yielding material cementedto the outer surface thereof, and a layer of flexible inelasticwaterproof material separate from the layer of yielding material, butcemented to the outer surface thereof.

2. A roll, consisting of a metallic core, a layer of fibrous materialcemented to the outer surface thereof and having its meeting edgesabutting against each other, and a layer-of oilcloth cemented to theouter surface of said layer of fibrous material and having its meetingedges abutting against each other, the whole being tightly rolled orcompressed during the operation of covering the core.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

JAMES B. HUDSON.
